Technical Specifications

  • Active Ingredient


    Chemical class: Piperininyl thiazole isoxazoline

  • Application Rate

    18.75 mg ai/1000 seeds, 14.1 ml/unit 150K

  • Formulations

    200 g/l Flowable Concentrate for Seed Treatment (FS)

  • Fungicide Group


  • Mode of Action

    Binds to oxysterol-binding protein (OSBP)

The active ingredient Oxathiapiprolin

  • Oxathiapiprolin, the active ingredient in Lumisena™, is active at every stage of the fungal life cycle, resulting in healthier plants.
  • It has preventative activity that inhibits zoospore release and prevents zoospore germination at very low concentrations as is evidenced below.
  • This protects from infection via the roots, enabling healthy emergence. 


Plasmopara halstedii lifecycle

  • Novel target site, completely new biochemical mode of action
  • Affects oxysterol-binding protein (OSBP)
  • Current FRAC Classification Number: 49
  • Function of OSBP still being investigated. Many functions in cell associated with OSBP's mostly dealing with signaling, lipid transport, membrane structure and hyphal tip growth.
  • No cross resistance with existing fungicides
  • Highly selective against Phytophytora and downy mildew species
  • Very low toxicity to a number of non-target organisms 

Key Benefits

- Very effective against oomycete pathogens that cause downy mildew

- Significantly better efficacy than market reference

- Increased emergence and healthier stand establishment to help secure yields

- Highly effective at very low active ingredient use rate

- New mode of action with no cross resistance to any existing fungicide

- Complements genetic resistance

- Favorable environmental profile

Environmental Profile

Lumisena™ has a favourable environmental profile if applied according to label recommendations.

It is very effective on target organisms at extremely low use rates and has very low toxicity to non-target organisms. Mammalian oral, neurological, developmental and dermal toxicity is low, as is avian and bee toxicity.

Resistance Management

Emergence tests EPPO vs between paper germination tests ISTA 4 hybrids, N rate and 2N rate, 3 and 6 months storage

Between paper germination tests ISTA 24 seed batches, 12 hybrids, 0-24 months of storage

Field trials: 13 efficacy tests, 19 selectivity tests France, Spain, Italy, Hungary, Romania, Bulgaria 6 hybrids included

No issues found 

Oxathiapiprolin is not cross-resistant with other classes of fungicides used against oomycete pathogens.

To reduce the risk of resistance development, Lumisena™ should be used in mixture with a different mode of action fungicide active on the target oomycete disease. 


Resistant management recommendation: Mefenoxam/metalaxyl-M (Apron XL)
